Not for: Climbers in parallel splitter cracks who need cams instead.
AI picks by need
For pin scars and flaring cracks
DMM Offset Nut (line)
Offset shapes seat in flaring placements and old pin scars that straight nuts cannot fit.
Not for: Beginners who still need simple, symmetrical nuts to learn placement.
For classic straightforward rack
Black Diamond Stopper (line)
Widely used, simple shape and sizes that match many guidebook rack lists.
Not for: Climbers seeking the most adaptable shape for irregular cracks.
For wide cracks without large cams
Black Diamond Hexentric (line)
Light, inexpensive wide-crack protection that cams into constrictions.
Not for: Climbers in parallel wide cracks, where hexes are hard to set.
What the AI looks for in Climbing Passive Protection Hardware
- Face shape
- Curved or tapered faces seat in more placements than flat ones; offsets for flaring cracks Contact area decides how reliably the nut holds.
- Set coverage
- Buy a complete set first, then add micro or offset nuts as needed Gaps in size force runouts or poor placements.
- Wire condition
- Retire nuts with kinked, frayed or broken wire strands Damaged wires fail well below a sound nut.
- Nut tool
- Always carry a nut tool when racking nuts Well-set nuts often cannot be cleaned by hand.
Brands that matter
- DMM: Wallnuts and offset nuts known for shape and precise forging.
- Black Diamond: Stoppers and Hexentrics, long-established standards.
- Wild Country: Rock nuts and hexes with a long trad heritage.
What to avoid
- Unbranded nut sets without recognized certification.
- Leading on tiny micro-nuts as primary protection before you can judge them.
- Using nuts with damaged wires.
Questions
Are micro nuts reliable?
They hold well in good rock when perfectly seated, but their small size means less margin, so treat them as backup rather than primary protection.
